EME107B KIT CONSTRUCTORS ALERT

This applies to all Kits between February 2007 & July 2008. There have been reports of low 10GHz output & increased 5GHz spur on the output of the multiplier. A number of Kits may have been supplied with NLB-300 devices instead of NLB-310. The marking on the components should be N6 for NLB-310. The NLB-300 marked N3, are quite fine to use but the two 51 ohm resistors should be changed to 68ohms to reduce the current in these devices to a suitable level. The output can be tuned with silver paint to produce up to +10dBm output on 10GHz.

BELOW SHOWS THE TESTED RESULTS OF THE PROTOTYPE KITS

ABOVE IMAGE SHOWS HOW THE PCB IS SOLDERED TO THE TIN OR BRASS STRIP. NOTE
THE USE OF 2 X SMA09 CONNECTORS THAT ARE SOLDERED DIRECTLY TO THE BOARD

ABOVE IMAGE SHOWS HOW THE PCB PINS ARE INSERTED INTO THE BOARD. ALL PINS
ARE CUT TO A LENGTH OF 6.35MM USING SHARP SIDECUTTERS & A VERNIER.

ABOVE IMAGE SHOWS THE PIPECAPS SOLDERED TO THE BOARD. NOTE THAT THE PCB
PINS THAT LOCATE THE PIPECAPS ARE PERMANANTLY LEFT IN PLACE.
